En carrying out my inventioiiyii isl n3 purpose to provide aconceneracor Wliicli will embrace the desired features ci el c ually andconveniently separae the valuableore from the Waele or diriJ with whichthe ore is mixed.

With the above-recited oojecs and others of a similar nature in View,tlie invention consists in the construction, combination and arrangementof parte, set forth and 'falling .vitliin the scope of Lilie appendedclaims.
